CANUTE H. MICKELSEN, OF BENCH, IDAHO.

HAY-STACKER.

Application led .'l'une 7, 1911.

To all whom t may concern.'

Be it known that l. CAXUTE H. MICKEL- SEX, a citizen of the llnited States, residing at Bench, in the county ot' Bannock and State of ldaho, have invented certain new and useful Improvements in Hay-Stackers, of which the following is a specification.

invention relates to hay stackers, and more especially to power-operated hay stackers. and the object of my invention is to provide means whereby the load of hay which is lifted by the elevator table may be deposited in any suitable place to be found upon the stack.

The invention consists of a base-trame upon which is rotatably mounted an upright suitably supportcd laterally by braces secured at their lower ends to the base frame and at their upper ends to a cap-piece torming a bearing for the rotatable upright. Booms are pivotally attached to the upright above the braces and at their outer ends there is an elevator table pivotally connected therewith. It projects beyond its pivotal connection with the booms, and a stay rod is connected thereto by a link connection and by a link connection with the upright. A hoisting mechanism is connected with the movable parts of the derrick.

rl`he objects of the invention are to provide a mechanism that will elevate the forkto a higher plane and to provide for a better transmission of power to raise the booms; to improve the construction of the booms whereby their strength and rigidity are increased; to provide improved means for controlling the elevator table; to provide means for tripping the elevator to discharge the load; and to provide means tor locking the upright in position when the elevator is` receiving and elevating the load.

1With these and otherl objects in view the invention presents a novel combination and arrangement of part-s as described herein, pointed out in the claims, and as illustrated by the drawings, wherein Figure 1 is a side view ot my invention, the elevator being lin a lowered position. Fig. 2 is a somewhat similar view to that shown in Fig. 1, the table, however, being elevated. Fig. 3 is a front view ot my invention, the 'table being in a lowered position. Fig. 4 is a side elevation ot the upright showing the manner oi' locking. lig. 5 is a front view of the locking means. Fig. 6 is an enlarged plan view oi the elevator Specification of Letters Patent.

table. Fig. 7 is an enlarged detail back view of the elevator table.

Referring now to the drawings for a more particular description: Figs. 1, 2 and 3 indicate a hay stacker which may be provided with any suitable base 3 so that the revolving upright 5 may be sustained, substantially in a vertical position. Upon the cross tie 2 of the base 3 is placed a bearing 32 for the purpose of receiving the lower end of the upright 5. The upright 5 is braced laterally by the braces 4, secured at their lower ends to the base 3 and at their upper ends to the cap 37. The top 38 and the bottom 39 of the cap 37 are tirmly secured to the upright 5. Roller bearings 52 are placed between the top 39 and the bottom 38 of the cap 37. rlhe said roller bearings are held in place by the bolts 53. By the revolving of the upright 5, the roller bearings 52 revolve around the inner face of the cap 37. Near the center of the upright 5 are firmly secured two collars 12. One of the collars is for supporting the booms 16, while the other one is for supporting the stay rods 31. Between vthe collars 12 and firmly secured to the upright 5 is a bracket 13 `tor the purpose of securing the locking device shown enlarged in Figs. 4 and 5. Near the upper end of the upright 5 and placed within the upright is a roller 16 over which passes the rope 11. vlUpon the top of the upright 5 is placed a cap 9 for the purpose ot securing the guy ropes 10. Between the collars 12 and the roller 16 and fulcrumed to the upright 5 is a tilting beam 6. A casting 8 is irmly secured to the upper end oi the tilting beam 6 tor the purpose of supporting the double tree B. A hole is cut near the lower end of the tilting beam. 6 for the purpose of allowing the rope 11 to pass through. An eye bolt 35 is secured through the lower end of the tilting beam o, to which is attached a pulley 26. rthe booms are secured to the collars 12 by lugs 'Z' and to the elevator table A by means oi' the bracket d5. The stay rods 31 are secured to the lugs on the collar by means of links 30, and to the nook 29 on the back ot the elevator A by :means of links 30. The hooks 29 are iirinly secured to the vertical brace 1T of the elevator table A. The vertical braces are iirmly secured together by means of horizontal braces 18. Secured to the back of the vertical braces 17 is a housing 19 for covering the spring catch 23. The spring catch 23 is for the purpose of securing and locking the elevator table 21 in a horizontal position by -hooking over the catch 20 which is firmly secured by means of lugs 20 to the cross tie 50 ofthe elevator table. The cross shaft 22 is secured to the elevator brackets 45, on which when tipping to unload the hay, the elevator table revolves. A spring 48 is placed around the shaft 22. One end of the spring 48 is secured at 51 to the elevator brackets 45; the other end is secured into plate 49 of the elevator table. The tripping lever 40, hinged to the locking spring 23, at 46, has a projecting arm 47 to which a rope is fastened.

The locking device, shown enlarged in Figs. 4'and 5, is secured to the upright 5 by means of a bracket 13 through which passes the rod 14. In the upper ends of the booms 16 is a lifting plate 15 pivotally secured. A hole is cut in the lifting plate 15 through which passes the lower end of the rod 14. The holes44 in the rod 14 are for the purpose of placing a bolt 43 for regulating the lift of the booms. The rod 14 is shown down with its lower end locked within the groove 42 of the cap 37. The lugs 43 on the cap 37 are for the purpose of receiving the upper ends of the braces 4. The pulleys 24, 25, 26, and 27 are to receive the power rope 28.

In the operation of my invention, I employ a power rope 28; said rope is secured to the tilting beam 6, at 34, thence brought down and under pulleys 24, thence up over pulleys 25, thence over pulley 26, and then down under pulley 27, then out to the power. By power being applied to the rope 28, the booms 16 to which elevator A is attached, are elevated to the required height by the draft upon the rope 28. By elevating the said booms 16, the lever `lifting device 15 in the upper end of said booms 16 is also elevated to come in contact with the bolt 43 in the rod 14, thereby lifting said rod out of the notch 42 in the fiange of the cap 37, thus allowing the elevator A to swing over the stack, by the turning of the upright 5. As soon as the elevatorhas reached the desired spot over thel stack, the operator pulls on the trip rope 56, thus cauusing the elevator table to trip and discharge the load. As soon as the load is off the table 21, the springs-18 turn the table back to its normal position. The dotted lines in Fig. 2 show the table tipped. I operate the tilting beam in the following manner: Rope 11 is secured to the bracket 8, then passes through the upright ,and over the roller 16', passed loosely down through a. hole in the lower end of said tilting beam 6,v thence through an eye bolt 36 secured in the upright 5 to within easy reach of the operator and secured around a hitchingI cleat at any convenient place on the main mast or stays. The rope 11 is used for raising and lowering the tilting beam 6, thus regulating the height of the lift for the elevator; the rope 11 is also tied through the eye bolt 36 and is within easy reach of the operator.

Having thus described my invention what I claim and desire to secure by Letters Patent, is
